stl2rsdocx v1.1 — now converts both directions

Convert into free DesignSpark Mechanical — and now export out to STEP / DXF. No subscription, no install.

Free DSM Explorer won't import STL/3MF/OBJ, and won't export STEP/DXF either — both are paid-Creator features. This tool bridges both gaps, on two tabs:

  • Convert (in → DSM) — STL / 3MF / OBJ / DAE / STEP → .rsdocx, then DSM's own free Convert to Solid makes it editable.
  • Export (DSM → out) — a mesh → STEP solid, 3D DXF, or 2D outline DXF, to send to a machine shop or another CAD package.

Download & run

Grab stl2rsdocx_gui.exe below, double-click, done. Windows only; nothing is installed.

⚠️ First run: Windows SmartScreen may warn about an unknown publisher — click More info → Run anyway. Normal for unsigned tools.

New in this release

  • 🆕 Export tab — get parts out of free DSM in formats it can't export itself:
    • STEP solid — opens in any CAD (SolidWorks / Fusion / FreeCAD) as a real solid body
    • 3D mesh DXF — for AutoCAD
    • 2D outline DXF — top / front / side, for laser / CNC / waterjet
  • SVG import — logos, outlines, laser shapes → extrude
  • DAE (COLLADA) import
  • STEP import rebuilt — exact face geometry (fixed a tessellation bug) plus a tessellated mesh option
  • Auto-scale parts saved in metres, auto-recenter offset parts, smarter auto-weld for 3MF artifacts
  • Analyze button — pre-flight check on how cleanly a part will rebuild
  • IGES / 3DS? The tool tells you to re-export as STEP / OBJ.

The free workflows

Get a mesh editable (in → DSM): Convert your STL/3MF/OBJ → .rsdocx (Smooth seams off) → open in free DSM → right-click → Convert to Solid → Merge faces → editable solid.

Send a part to a machine shop (DSM → out):

  1. In DSM: File → Save As → STL (free) at the finest tessellation.
  2. In the Export tab: drop the STL, choose STEP solid, Export.
  3. Send the .step — it opens in any CAD as a solid.

Honest limits

  • Convert to Solid and exported STEP/DXF are faceted — round bores become many-sided polygons (it's a mesh underneath). Great for flat / prismatic parts; for tight round tolerances use the finest tessellation, or paid Creator's true STEP export.
  • STEP is verbose (~1 KB per triangle) — reduce dense meshes first.
  • Export reads meshes (rsdocx / STL / OBJ / 3MF), not native Parasolid solids — hence the STL step above.
  • Want true smooth curves? Get the part as STEP, or use Fusion / Blender.
